PERIMETER ADHESIVE FOR IMPROVED RELIABILITY AND REDUCED STRESS MURA IN CURVED DISPLAYS WITH COVER GLASS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240053629 titled 'PERIMETER ADHESIVE FOR IMPROVED RELIABILITY AND REDUCED STRESS MURA IN CURVED DISPLAYS WITH COVER GLASS

Simplified Explanation

The patent application describes a curved display assembly with a glass sheet and a curved display bonded together with adhesives of different elastic moduli.

  • Glass sheet with first and second major surfaces, second surface having a first curvature with a bend axis
  • Curved display with second thickness between first and second display surfaces, display region and overhanging edges parallel to bend axis
  • First adhesive bonds second display surface to second major surface in display region
  • Second adhesive between overhanging edges and second major surface, with higher elastic modulus than first adhesive
  • Overhanging edges extend at least three times the second thickness outside display area

Potential Applications

  • Curved displays for electronic devices
  • Automotive displays
  • Curved monitors for gaming or entertainment systems

Problems Solved

  • Bonding curved displays to glass sheets
  • Ensuring structural integrity of curved display assemblies
  • Preventing delamination or separation of display components

Benefits

  • Improved durability and reliability of curved displays
  • Enhanced aesthetics and design possibilities for electronic devices
  • Potential for thinner and lighter curved display assemblies


Original Abstract Submitted

embodiments of a curved display assembly are disclosed. the assembly includes a glass sheet having first and second major surfaces. the second major surface defines a first curvature of the glass sheet, and the first curvature has a bend axis. the assembly also includes a curved display having a second thickness between first and second display surfaces. the display has a display region and two overhanging edges adjacent to the display region and parallel to the bend axis. a first adhesive bonds the second display surface to the second major surface in the display region. a second adhesive is disposed between each of the two overhanging edges and the second major surface. the second adhesive has a higher elastic modulus than the first adhesive. the overhanging edges each extend a distance outside of the display area that is at least three times the second thickness of the curved display.
